Title: Focus detector
Inventor: HAMADA MASATAKA
IPC: G02B7/34
Filed: 1985-10-12
Abstract: PURPOSE:To simplify arithmetic processing for range finding by fixing a difference value on a prescribed value when an overflow is generated at the calculation of a difference by a difference arithmetic means. CONSTITUTION:Output from respective picture elements in a CCD image sensor 20 are successively converted into digital signals D(X) by an A/D converter 24 and inputted to a four-picture element delay circuit 28 to delay four picture elements. A subtractor 30 calculates the difference DELTAD(X) between the raw picture element data and the data D(X+4) delayed by four picture elements and outputs the difference data DELTAD(X) successively. The difference data DELTAD(X) is inputted to an overflow checking circuit 32, and if an overflow is generated in the difference data DELTAD(X), a data correcting circuit 34 fixes the DELTAD(X) on maximum data generating no overflow and outputs the fixed value. When no overflow is generated in the DELTAD(X), the data correcting circuit 34 outputs the difference data DELTAD(X) as they are.

Title: Electromagnetic propulsion device
Inventor: INOUE WAHEI
IPC: H02K44/06
Filed: 1987-09-10
Abstract: PURPOSE:To prevent the generation of gas and get rid of the occurrence of noise and vibration by providing plural exciting coils on the outer periphery of a fluid-passable cylinder body having an insulating property while covering the exciting coils with a magnetic shielding body. CONSTITUTION:An electromagnetic propulsion device body 1 has a cylinder body 2 on which exciting coils 3 are externally installed. By filling the inside of the cylinder body 2 with sea water and, as a three-phase alternative current is applied to the exciting coil 3 in a superconducting condition, a strong magnetic field is generated in the axial direction of the cylinder body 2 while inducing an eddy current in the perpendicular direction thereto. As a result, a repulsive force is generated in the axial direction of the cylinder body 2, obtaining a propulsion force. In this case, a magnetic shielding body 5 becomes a nonmagnetic material due to a Meissner effect forming a magnetic path in a space part. Hence, by introducing sea water from an introducing pipe 12, a ship can advance effectively. Thereby, no gas is generated because there is no electrode, neither causing noise nor vibration.

Title: Non-power driving thermal transfer type cooling device and its driving method
Inventor: YONEDA ISAMI
IPC: F25B1/00
Filed: 1995-09-05
Abstract: PROBLEM TO BE SOLVED: To reduce an energy consumption amount during a defrosting operation and to shorten a defrosting operation time by a method wherein a liquid reservoir and a valve for opening or closing a liquid down-pipe passage are arranged in the midway part of the liquid down-pipe passage in a cooling device in which refrigerant is circulated between an upper condensing device and a lower evaporating device. SOLUTION: Refrigerant which retrieves heat around an evaporating device 2 and evaporates during a normal operation of a cooling device passes through a gas returning pipe 4, enters a condensing device 1, where the refrigerant is cooled by cooling liquid there and liquefied, thereafter the refrigerant passes through a liquid down-pipe 3a and flows down into a liquid reservoir 5. Then, a part of the refrigerant overflown from the liquid reservoir 5 passes through the liquid down-pipe 3b, flows into the evaporating device 2 so as to constitute a closed cycle. In turn, during a defrosting operation, the liquid refrigerant in the liquid reservoir 5 is heated by an electrical heater 9 and evaporated and concurrently the opening or closing valve 6 is closed and liquid refrigerant in the liquid reservoir 5 is gasified.  With such an arrangement as above, the liquid refrigerant in the evaporating device 2 passes through the gas returning pipe 4, is pushed into the condensing device 1 and recovered.
